first of all look for your triaxis midi channel, even try to test with th midi-ox software to test the midi connections, if this fails, then you have a failure on your midi logical components, for example with the adart, that is the interface of inputs and outputs that links the external of the triaxis with the main cpu, for example, midi, front controls... you can also check the midi optocopleur that adapts signal in/out of the midi, it is a 6 or 8 ic pins typical called something like 6n136,137,138, even i could do a better research to say what other elements could be failing, of course check first your cables and pedalboard, even i could repair your TA but it will cost to you 10000 dollars, :roll: maybe quit some 0 of the bill
